Filter by:Neoadjuvant systemic treatment for breast cancer (used in locally advanced and operable breast cancer) includes anthracycline based chemotherapy (Doxorubicin/Cyclophosphamide) followed by taxanes (weekly Paclitaxel or Docetaxel) with antiHer-2 Trastuzumab or dual antiHer-2 Trastuzumab plus Pertuzumab. Other regimens include Docetaxel plus Carboplatin plus Trastuzumab alone or combined with pertuzumab for Her-2 positive patients. The tumor microenvironment, which includes extracellular matrix and stromal cells, is a key factor in tumorigenicity and the prediction of the efficacy of immunotherapy, conventional chemotherapy, and other anticancer therapies. Tumor-infiltrating lymphocytes (TILs), one of the most important components of the tumor microenvironment, were reported to predict the response to NAC both for tumors and axillary lymph nodes in breast cancer patients. This study is conducted to examine the relationship between tumor-infiltrating lymphocytes (categorized into three levels) and the pathologic complete response to neoadjuvant systemic therapy in breast cancer patients, and to examine the relationship between TILs and 1-year invasive disease-free survival (IDFS).
One of the primary criticisms of mammography is that it leads to unneeded stress and anxiety from identification and biopsy of non-cancerous findings. Contrast-enhanced mammography (CEM) has the potential to significantly reduce biopsy rates for commonly seen benign breast lesions while preserving very high cancer detection. The investigators propose a prospective clinical study of patients with diagnostic mammograms rated as BIRADS 4A or 4B and scheduled for a biopsy, in which, prior to undergoing their scheduled biopsy, a CEM procedure is performed. The investigators will test the primary hypothesis that for soft tissue lesions (i.e. masses, asymmetries, architectural distortions) initially rated BI-RADS 4A/4B adding CEM will reduce, by at least 20%, the number of biopsy recommendations for actually benign cases and, at the same time, provide a negative predictive value (NPV) higher than 95%.
This study is a prospective, open-label, phase II clinical study for patients with HR+/HER2- advanced breast cancer.
This study will test any good and bad effects of combining the study drugs pembrolizumab and olaparib, given before the standard surgical procedure, to treat TNBC or HR+ HER2- breast cancers. The study drugs could shrink cancer, but they could also cause side effects. The study researchers want to find out whether the study drugs will shrink the cancer by a certain percentage compared with its current size, which may improve the outcome of surgery.
Breast cancer is the most common malignancy among females. Nearly 40-60% of breast surgery patients experience severe acute postoperative pain, with severe pain persisting for 6-12 months in almost 20-50% of patients (post mastectomy pain syndrome) which is defined according to International Association for the Study of Pain (IASP) as pain which persists more than 3 months after mastectomy/lumpectomy affecting the anterior thorax, axilla, and/or medial upper arm. Regionale anesthesia is one of the strategies with the potential to prevent the development of chronic pain following breast surgery. We hypothesize that erector spinae plane block is going to be more effective than serratus anterior plane block in the prevention of postmastectomy pain syndrome.
Postoperative breast radiotherapy (RT) has been associated with increased risk of heart toxicity. However, there is a lack of knowledge for radiation-induced early cardiovascular injury, especially for hypofractionated RT. This study aims to prospectively detect and predict early clinical or subclinical cardiac events in women undergoing adjuvant RT for breast cancer.
Breast cancer is the most commonly diagnosed cancer, with an estimated 2.3 million new cases per year globally. Approximately 90% of these patients will undergo breast surgery with/without radiation (locoregional treatment). Different surgical techniques can be offered to the patient, each leading to completely different aesthetic outcomes. Moreover, the aesthetic outcome could be completely different for patients undergoing the same surgery based on individual patient factors (e.g., age, body habitus). In the CINDERELLA trial, the investigators will be using the (Breast Locoregional (BreLO) AI system (an artificial intelligence-based tool for the classification of aesthetic outcomes and matching data and photographs) integrated into CANKADO (a cloud-based healthcare platform) to create an easy-to-use application that can be used on any electronic device, to simulate visually to the patient the aesthetic outcome of a certain surgery or radiation treatment. In the CINDERELLA trial, the investigators plan to compare whether the application helped fulfil the expectations and lead to a better quality of life compared with the classical approach. In the classical approach (control arm), doctors usually propose a locoregional treatment and explain theoretically how the result will be. Nurses help by explaining further details about the surgery and possible outcomes. In most centres, no photographic evaluation is done, and expectations are not measured. The CINDERELLA trial will help overcome miscommunication and potential boundaries in the patient's or physician's understanding of the potential outcomes of locoregional breast cancer treatment.
Patients who have undergone curative treatment may be at risk of relapse. This study will collect, annotate, and sequence biospecimens (blood, stool, and tissue) from patients across different tumor types to detect molecular residual disease (MRD) before metastases become radiographically or clinically detectable. This will allow for early cancer interception, and hopefully prolong relapse-free survival across tumor types.
The investigators propose a randomized controlled trial to determine the effectiveness of inspiratory muscle training in improving exercise tolerance among stage 0-III obese breast cancer survivors.
Breast cancer (BC) survivors will experience multiple symptoms following chemotherapy. During the pandemic of COVID-19, the closure of clinics and fear of infection lead to BC patients' challenges in self-managing their multiple symptoms in home settings. Mobile health (mHealth), without time and space limitation, plays a positive role in supporting self-management and treatment compliance. However, previous mHealth self-management studies did not report sustained beneficial effects with physician-led supervision. In oncology practice, the nurse-led model of patient self-management for breast cancer has been placed on greater emphasis. Accordingly, an innovative nurse-led supervised mHealth program was designed to support self-management for BC patients undergoing chemotherapy. This pilot study aims to examine the feasibility and acceptability of a nurse-led mHealth-based self-management program for BC patients receiving chemotherapy, in order to provide evidence for conducting a definitive trial. The feasibility outcomes of the pilot study include subject eligibility rate, recruitment rate, and retention rate. The efficacy outcomes relate to self-efficacy (primary outcome), symptom distress and frequency, as well as health-related quality of life, and healthcare utilisation. The qualitative outcomes encompass patient- and provider-users' perceptions of the app usability and subjects' experiences of engaging in the pilot study.
